I've got Javascript projects of a couple of years old. There are certainly things I'd do differently now if I were to set them up today, but I wouldn't consider that technical debt: those things are not giving me practical problems in the foreseeable future. The only of such projects that I'm still running which does have significant technical debt, from my point of view, is the one I set up without a CI system and without a package manager with a lock file (those didn't exist back then) - I cannot update that code today, because I cannot build it. Rewriting that one with a reproducible build set up is something I consider tech debt and which is still on my TODO list of intending to solve one day.
